BOTTLE-CAP REMOVER.

Application filed March '7, 1922.

To @ZZ whom t may 01m-cera:

Be it known that I, LESLIE A. TYLER, a citizen of the United States, anda resident of Salamanca, in the. county of Cattaraugus and State of NewYork, have invented a new and Improved Bottle-Cap Remover, oi which thefollowing is a full, clear, and exact description.

This invention relates to improvementsin bottle cap removers,particularly a device for removing the usual paste-board cap from milkbottles, an object of the invention being to provide a device of thischaracter which will be entirely sanitary, which will be simple andpractical in construction, eilicient in use and inexpensive tomanufacture.

A still further object is to provide abottle cap remover which may bevery easily operated and which will prove a great convenience tohousewives.

With these and other objects in view, the invention consists-in certainnovel features of construction and combinations and arrangement-s ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings Figure l is a view in section through myimproved bottle cap remover showing same in applied and operativeposition.

Figure 2 is a top plan view thereof.

Referring in detail to the drawings, I have used the reference numeral lto designate a milk bottle and 2 represents the usual type of pasteboardbottle cap or stopper forced into the mouth of the bottle and serving asa closure therefor.

My improved cap remover includes a eircular plate 3 and a frame 4 risingfrom the plate. 'The plate is substantially the same size as the usualmilk bottle cap and the frame 4c may be integral therewith, solderedthereto or otherwise suitably connected. A pointed plunger 5 is mountedin the frame l at an oblique angle to the plane of the plate 3. Theupper intermediate portion of the frame l is provided with an opening 6.accommodating the intermediate portion of the plunger 5 and an obliquelyextending opening 7 normally accommodating the lower pointed end of theplunger is provided in the plate 3.

A stop ring 8 fixed to the intermediate portion of the plunger isnormally held in engagement with the frame by coiled ex Serial No.541,699.

pansion spring 9 around the plunger between the ring and the plate 3.Movement of the plunger in the other direction against the action of thespring is limited by the engagement of a handle l0 with the frame 4f.

In operation the plate is placed upon the cap, the spring 9 normallyholding the pointed end of the plunger in retracted position within theopening or passage 7. The handle 10 is pushed downwardly with the palmof the hand, causing the plunger 5 to pierce the bottle cap. While theplunger is vin this depressed position the operator uses the frame e asa handle, fulcruming the plate 3 on one of its edges so that the handlel0 moves in the direction of the arrow. By virtue of the engagement ofthe pointed end of the plunger with the cap as indicated in dotted linesin Figure l this fulcruming or lifting plate 8 will remove the cap fromthe bottle and as soon as the handle lO is released the plunger willspring back and the cap will be dropped from the plate.

The plunger and the opening through which it moves are inclined atangles of less than 90 degrees with respect to the fulcruming edge ofthe plate. By this arrangement, when the handle l0 is moved in thedirection of the arrow, the pointed end of the plunger being inengagement with the cap, the plate will rock on its fulcrum edge andeii'ect removal of the cap from the bottle.

It will be apparent from the foregoing description that I provide a capremoving device which may be very easily operated and very easilysterilized. It is to be understood, however, that while I haveillustrated the preferred embodiment of the invention numerous slightchanges and alterations might be made in the general form andarrangement of parts described without de.- parting from the inventionand hence I do not wish to limit myself to the precise details setforth, b-ut shall consider myself at liberty to make such slight changesand alterations as fairly fall within the spirit and scope of theappended claims:

1 A bottle cap remover comprising a plate adapted .to engage a discstopper of a closed receptacle and having an inclined openingtherethrough, the length of said plate being coextensive with thediameter of the stopper, a frame carried by the plate and being providedwith an inclinedv opening in alinement with the opening in the plate,and an inclined plunger mounted on the frame and plate and movablethrough said openings to pierce the stopper, said plunger being extendedbeyond the frame a distance, whereby the plate may be rocked on its edgeremote from the plate opening to effect removal of' the stopper.

2. A stopper extractor comprising a circular plate adapted to engage adisc stopper and having an area coincident With the area or' thestopper, saidA stopper provided With an orifice adjacent to itsperiphery, a pointed plunger mounted on said plate in alinement withsaid orifice and inclined with respect to said plate, and a lever handlecarried by said plunger, whereby said plunger may be forced through saidorilice to pierce the stopper and rock the plate on its periphery as afulcrum to effect removal oi' the stopper'.

3. A bottle cap remover comprising a circular plate adapted to engage adisc stopper, the area of the plate being coincident With the area ofsaid stopper, said plate having an inclined opening therethrough. aframe carried by said `plate and provided With an inclined opening inalinement with the opening of the plate, and an inclined plunger mountedon the frame and plate and movable through said openings to pierce thestopper, said plunger extending beyond the tra-me a distance whereby theplate may be rocked on its edge, remote from its opening to effect theremoval of the stopper.

4. A bottle cap remover comprising a plate adapted to engage a discstopper held on an annular shoulder Within the neck of a bottle andhaving an inclined opening therethrough adjacent one end, the oppositeend of said plate approximately extending to the periphery of saidstopper and over the/aforesaid shoulder, and apointed plunger mounted onsaid plate and movable through said inclined opening in the plate, saidplunger and the opening through which it moves being inclined at anangle of less than 9() degrees With respect to the end of the platewhich extends over the shoulder of the bottle, said plunger extendedbeyond the plate a distance whereby the plate may be rocked on its edgeremote from the plate opening as a fulcrum to effect removal of thestopper.
